Wolves vs. Cougars: New Study Reveals Who Really Dominates Yellowstone
From SciTechDaily.com:
New research shows that encounters between wolves and cougars in Yellowstone National Park are shaped mainly by wolves taking over prey that cougars have already killed. The study also finds that cougars reduce the risk of these encounters by shifting their diet toward smaller animals, which they can consume more quickly and abandon before wolves arrive.
